Pagodas are tower-like structures often characterized by multiple eaves stacked on top of another. Seen throughout Asia, pagodas are adaptations of India’s Buddhist stupas, which were initially built to house the remains and relics of the Buddha. As Buddhism spread throughout Asia, stupas became a vital feature of Buddhist temples and their traditional dome shape slowly evolved into what we now know as a pagoda. Similar to stupas, pagodas were initially used to hold Buddhist relics, though many have since lost this function. The number of eaves on a pagoda sometimes has a symbolic meaning. In Japan, for example, it’s common to see pagodas built with five different tiers. These represent nature’s five elements: earth, fire, water, wind, and space.
